An English verb meaning "to release flatulence", which can be applied to people with Crohn's disease. These generally cause extremely foul odors and are known to stimulate symptoms in unfortunate bystanders that can range from minor heart attacks to death. Those who crohn are advised to isolate themselves for at least two minutes before making any human contact, but four hours is the physician-recommended amount.
